Deskripsi
The title compound [systematic name: N,N-diethyl({[(diethylcarbamothioyl)sulfanyl]selanyl}sulfanyl)carbothioamide], C10H20N2S4Se, crystallizes in a new form in the space group Pca21: the previously reported polymorph crystallizes in the space group P212121. The new phase contains two independent molecules in the asymmetric unit. The Se atoms are tetracoordinated, with a distorted square-planar geometry. The ligands coordinate asymmetrically to the Se atoms, with one strong Se—S bond [range 2.2833 (13)–2.3041 (15) Å] and one weaker bond [range 2.7318 (14)–2.7873 (12) Å].
